摘　　要：以贵港市马来河作为典型中小河流,选取一维水质数学模型,通过污染物综合降解系数、设计水文条件、初始断面污染物浓度、水质目标浓度等参数的率定,计算得马来河水功能区2020年、2030年的纳污能力,为贵港市控制污染物排放工作提供技术支撑。In order to provide technical support for Guigang’s efforts to control pollutant emission,Malai River was selected as a typical small and medium-sized river for analysis.A one-dimensional water quality mathematical model was established.The parameters such as the comprehensive degradation coefficient of pollutants,the design hydrological conditions,the pollutant concentration in the initial section and the target concentration of water quality were calibrated.The environmental capacity of the water function areas of Malai River in 2020 and 2030 was calculated.
